v1.12.0-dev

1. Enhancements

EEx

  • [EEx.Engine] Add c:EEx.Engine.handle_text/3 callback that receives text metadata
  • [EEx.Engine] Emit warnings for unused "do" expression in EEx

Elixir

  • [Code] Do not add newlines around interpolation on code formatting. Note this means formatted code that has interpolation after the line length on Elixir v1.12 won't be considered as formatted on earlier Elixir versions
  • [DateTime] Add offset to DateTime.to_iso8601/2 (now to_iso8601/3)
  • [Enum] Add Enum.count_until/2 and Enum.count_until/3
  • [Enum] Add Enum.product/1
  • [Enum] Add Enum.zip_with/2 and Enum.zip_with/3
  • [Enum] Add support for functions as the second argument of Enum.with_index/2
  • [Float] Add Float.pow/2
  • [Integer] Add Integer.pow/2
  • [List] Add default value for List.first/1 and List.last/1
  • [Kernel] Also warn for literal structs on min/2 and max/2
  • [Kernel] Add Kernel.tap/2 and Kernel.then/2
  • [Kernel] Do not add runtime dependencies to remotes in typespecs
  • [Kernel] When there is an unused variable warning and there is a variable with the same name previously defined, suggest the user may have wanted to use the pin operator
  • [Module] Add Module.get_definition/2 and Module.delete_definition/2

  • [Stream] Add Stream.zip_with/2 and Stream.zip_with/3
  • [String] Add :turkic mode option to String case functions
  • [Tuple] Add Tuple.sum/1 and Tuple.product/1

ExUnit

  • [ExUnit] Intercept SIGQUIT and show a list of all aborted tests as well as intermediate test results

IEx

  • [IEx] Make IEx' parser configurable to allow special commands
  • [IEx] Show function signature when pressing tab after the opening parens of a function

Mix

  • [Mix] Support :exit_code option in Mix.raise/2
  • [Mix] Discard MIX_ENV and MIX_TARGET values if they are empty strings

2. Bug fixes

Elixir

  • [CLI] Ensure -e "" (with an empty string) parses correctly on Windows
  • [Kernel] Preserve CRLF on heredocs
  • [Kernel] Public functions without documentation now appear as an empty map on Code.fetch_docs/1, unless they start with underscore, where they remain as :none. This aligns Elixir's implementation with EEP48
  • [Kernel] Do not crash when complex literals (binaries and maps) are used in guards
  • [Macro] Macro.decompose_call/1 now also consider tuples with more than 2 elements to not be valid calls
  • [OptionParser] Properly parse when numbers follow-up aliases, for example, -ab3 is now parsed as -a -b 3
  • [Path] Fix Path.relative_to/2 when referencing self

IEx

  • [IEx] Fix auto-completion inside remote shells

Mix

  • [mix compile.elixir] Ensure that a manifest is generated even with no source code
  • [mix compile.elixir] Make sure export dependencies trigger recompilation when removed

3. Soft-deprecations (no warnings emitted)

4. Hard-deprecations

EEx

  • [EEx.Engine] use EEx.Engine is deprecated in favor of explicit delegation

Elixir

  • [Kernel] Deprecate @foo() in favor of @foo
  • [System] Deprecate System.stacktrace/0 (it was already deprecated outside of catch/rescue and now it is deprecated everywhere)

Mix

  • [mix compile] The :xref compiler is deprecated and it has no effect. Please remove it from your mix.exs file.
